Patented Dec. 19, 1911 Application filed Karen 11,; 181i. seriai'irb. 613,700.

To all whom 'it m: Be it known that we, WILLIAMS. BENSON JosnPH BREELOFE,.bOtl1. citizens of th' United States, and residents of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and ImprovediPhotographic Plate, of which the following is a full, clear, .and exact description.

This invention relates to a new and im; proved photographic plate of a type adapts ed to be constructed of some thin material, such as metal, and to be used inmagazine cameras.

It has been found that in such types of magazine cameras as use thin metallic:- plates in packs, it has been difiicult to sepa-' rate the several plates from each other, in, order to feed each successive plate in opposition to the lens. I c

It is therefore an object of this invention to providea camera'plate with means for affording suflicient space between the separate plates When arranged in a pack, to give the required clearance, so that one plate can be separated from the others.

A further object of this invention is to provide a camera plate which will be extremely thin, .and yet which will afiord'the desired clearance without the wasting of any excessive metal, and without the necessity of any complicated mechanism for. forming the same;

These and further objects, together with the construction and combination ,of parts, y will be more full described hereinafter and particularly set orth in the, claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all theviews, and in which c Figure 1 is a face view of one of the plates; Fig. 2 shows two juxtaposed plates. in perspective, brin 'ng out their relative positions, whereby t e alternate plates are staggered when placed in a pack, so that the ofi'sets will intersect each other at an angle, thereby affording the proper clearance; and Fi 3 is a top plan view, showing a series 0 plates in a pack.

Referring more particularly to the details of th1s invention as embodied in the form shown in the drawings, 1 indicates a photographic plate, which may be of any suitable material, such as sheet metal, and

gcross at an angle, thereby preventing the f; which'nia ,be coated, with ,asensitive of any sul able character.

:It will be notedthat, thepl'ate is stam .ed, ei lpanded, or punched out 'adjacentits' gs ,tocform a plurality of ofl'sets 3, 4, 5 and 6. These ofl'sets are arranged in pairs, which 'may slope. toward each other, with the pair at one end slopingin substantially the same direction as the pair at the other end, although the angle maybe slightl different,

desired. The main idea is to ave opposite offsets extending in angular relatlon with respect to each other, so that when two plates are placed in (other, with one end 0 one adjacent the o posite end of the other, and facing in t e same direction, the ofisets of one, in this in- ;stance represented at 6 and 5, will be op- {posite the ofi'sets of the other, represented at "3 and 4, as indicated in Fig. 2, so that they oflt'sets fitting into each other, thus a rding the necessary clearance, due to the amount of the extension of the ofisets.

While we have shown one embodiment of our invention, we do not wish to be limited to the specific details thereof, but desire. to V be protected in various changes, alterations and modifications which may come within the scope of the appended claims.

Having thus described our invention, we j claim as new and desire to secure by Letters =P'atent: j

1. A photographic plate, comprising a sheet having portions adjacent the edges thereof stamped out to form ofisets adapted to space said plate apart from a similar plate when said lates are laced in con tact with each 0t er, said 0 sets being arranged in pairs, the members of the pairs slo ing toward each other, the members of eac pair sloping in substantially the same direction as the corresponding members of the other pairs.

2. A camera pack, comprising a plurality of thin plates arranged in juxtaposition to each other, each plate having a series of ofi'sets arranged in pairs in angular relation with respect to eac other, the members of each pairbeing substantially parallel to the corresponding members of the other pair, each alternate plate being inverted with respect to the 'ad'acent plates so. as to have t e adjacent 0 sets on the adjacent plates extending at angles to each other.

3. A photographic plate, comprising a sheet having portions adjacent the edges thereof stamped out to form ofl'sets having sets of one plate fitting into the olisets of the other plate.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
